A sphere has a diameter of 6 ft. Find the volume of the sphere.

some help please

exact = 36pi , rounded = 113.097

Step-by-step explanation:

The volume of a sphere is 4/3*pi*r^3

a radius is half of a diameter, so the radius is 3 ft.

4/3*pi*3^3

3 cubed equals 3*3*3 which equals 27.

so, now you get 4/3*pi*27

so you get approximately 113.097, or 36pi

Hope this helps!

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
